{{Article quote|Infiltrate a [[Forerunner]] [[Threshold gas mine|facility]], quell the [[Heretics|heresy]] within.}}

'''The Arbiter''' is the sixth [[campaign]] level of ''[[Halo 2]]'', where the [[Arbiter]] [[Thel 'Vadam]]ee is introduced as a playable character for the first time. You must assassinate the [[Sesa 'Refumee|Heretic Leader]] on a [[Forerunner]] [[Threshold gas mine|gas mine]] in [[Threshold]]'s atmosphere.

The mission involves neutralizing [[Sesa 'Refumee's heretic faction|Heretic]] forces. Along the way, the player will have to open a hangar door for reinforcements, fight, for the first time in ''Halo 2'', [[Sentinel]]s, and fly a [[Banshee|Heretic Banshee]] to escort a friendly [[Phantom]] that is looking for where the Heretic Leader escaped to.

This is also the first time in ''Halo 2'' you are able to use the [[Covenant Carbine]], the [[Sentinel Beam]], and the [[Fuel Rod Gun]]. It is also the first time members of the Covenant aid you. Your allies are [[Special Operations Officer]] Elites and [[Special Operations Grunts]], meaning that you start off with rather powerful friendly units.

[[File:H2A - Kig-Yar convicts.jpg|thumb|300px|Jailed Jackals reaching out of the cell.]]

''A blurry camera shot focused on the floor, before clearing and focusing on the back of [[Tartarus]]. The shot then changes to show Tartarus walking down a hallway in ''[[High Charity]]'', two [[Jiralhanae]] behind him, carrying Thel 'Vadamee on their shoulders. They are walking through a prison.''

----
'''Anniversary version'''

''Scene opens on a pair of imprisoned [[Kig-Yar]] sticking their heads out of their jail cell, snarling. Camera shifts to the right to show Tartarus walking down the corridor, flanked by two Jiralhanae carrying 'Vadamee on their shoulders.''
----

*'''Jiralhanae 1''': "How much further must we heft this baggage? Any cell will do."

*'''Jiralhanae 2''': "Why not toss him in with this lot?"

''The Jiralhanae pass a cell containing three hungry [[Kig-Yar]], which hiss and growl as they reach out through the bars at the Jiralhanae passing by.''

*'''Jiralhanae 2''': "They could use the meat."

*'''Jiralhanae 1''': "Them? What about ''us''? My belly aches - and his flesh is seared, just the way I like it."

*'''Tartarus''': "Quiet! You two whimper like [[Unggoy|Grunts]] fresh off the [[Food nipple|teat]]. He's not meant for the jails. The [[Hierarchs]] have something special in mind."

''The Jiralhanae and their cargo move out onto a platform overlooking the [[Mausoleum of the Arbiter]]. They ride a [[gravity lift]] down to the walkway leading up to it and pass dozens of [[Sangheili Honor Guardsmen]] standing at attention, [[energy staves]] ready. They enter the Mausoleum, where the [[Hierarchs|High Prophets]] of [[Prophet of Truth|Truth]] and [[Prophet of Mercy|Mercy]] await. The three Jiralhanae bow, forcing 'Vadamee to do the same.''

*'''Tartarus''': "Noble Prophets of Truth and Mercy. I have brought the incompetent."

''Close-up on the Prophet of Truth's lower jaw.''

*'''Prophet of Truth''': "You may leave, Tartarus."

''Tartarus looks up, surprised.''

*'''Tartarus''': "But...I thought—"

*'''Prophet of Truth''': "And take your Brutes with you."

''Tartarus hesitates, and then bows again.''

*'''Tartarus''': "Release the prisoner."

''The Jiralhanae drop 'Vadamee to his knees and rise, leaving the room. The [[Sangheili]] touches the [[Mark of Shame]] on his chest.''

*'''Prophet of Truth''': "The [[High Council|Council]] decided to have you hung by your entrails and your corpse paraded through the city. But ultimately, the terms of your execution are up to me."

*'''Thel 'Vadamee''': "I am already dead."

*'''Prophet of Truth''': "Indeed. Do you know where we are?"

*'''Thel 'Vadamee''': "The Mausoleum of the Arbiter."

*'''Prophet of Truth''': "Quite so. Here rests the vanguard of the [[Great Journey]]. Every [[Arbiter]], from first to last. Each one created and consumed in times of extraordinary crisis."

*'''Prophet of Mercy''': "The [[Taming of the Lekgolo|Taming of the Hunters]], the [[Unggoy Rebellion|Grunt Rebellion]] - were it not for the Arbiters, the [[Covenant]] would have broken long ago!"

*'''Thel 'Vadamee''': "Even on my knees, I do not belong in their presence."

*'''Prophet of Truth''': "[[Installation 04|Halo]]'s destruction was your error, and you rightly bear the blame. But the Council was... overzealous. We know you are no heretic. ''This'' is the true face of heresy, one who would subvert our faith and incite rebellion against the High Council."

''Truth presses a button on his chair and a miniature hologram of a Sangheili in abnormal equipment appears.''

*'''[[Sesa 'Refumee]] (Hologram)''': "Our [[San'Shyuum|Prophets]] are false! Open your eyes, my brothers! They would use the faith of our forefathers to bring ruin to us all! The Great Journey is a-"

''Truth cuts off the hologram.''

*'''Prophet of Truth''': "This heretic, and [[Sesa 'Refumee's heretic faction|those who follow him]], must be silenced."

*'''Prophet of Mercy''': "Their slander offends all who walk the Path!"

*'''Thel 'Vadamee''': "What use am I? I can no longer command ships, lead troops into battle-"

*'''Prophet of Truth''': "Not as you are, no. But become the Arbiter...and you shall be set loose against this heresy with our blessing."

''A large pod floats into the center of the room, opening to reveal a suit of ancient armor surrounded by white light. 'Vadamee stares at this for a moment, before turning back to Truth.''

*'''Thel 'Vadamee''': "What of the Council?"

*'''Prophet of Mercy''': "The tasks you must undertake as the Arbiter are perilous, suicidal. You will ''die'', as each Arbiter has before you. The Council will have their corpse."

[[File:MercyTruthArbiter.jpg|thumb|300px|Thel 'Vadmaee being offered the title of Arbiter and the body armor.]]

''Thel 'Vadamee rises and walks toward the armor. He pauses before it, and looks to the pods containing the bodies of the Arbiters who fell before him. He reaches up and takes the helmet of the Arbiter, and places it upon his head. He turns to the Hierarchs.''

*'''Thel 'Vadamee''': "What would you have your Arbiter do?"

''The scene changes to show the outside of High Charity, the fleet surrounding it. Three [[Kez'katu-pattern Phantom|Phantom]]s fly past the camera and swoop past the ruins of [[Installation 04]], a large piece of it still intact and with landscape and clouds still visible. As it flies, the voice of [[Special Operations Commander]] [[Rtas 'Vadum]]ee can be heard.''

*'''Rtas 'Vadumee''': "When we joined the Covenant, we took an [[Writ of Union|oath]]!"

*'''Special Operations Sangheili''': "According to our station! All without exception!"

''The scene cuts to the inside of the center Phantom, where [[Special Operations Sangheili]], along with the [[Thel 'Vadam|new Arbiter]], line the walls, with a line of [[Special Operations Unggoy]] in the center. The white-armored [[Sangheili]] [[Special Operations Commander]] Rtas 'Vadumee, walks among them.''

*'''Rtas 'Vadumee''': "On the blood of our fathers, on the blood of our sons...we swore to uphold the Covenant!"

*'''Special Operations Sangheili''': "Even to our dying breath!"

*'''Rtas 'Vadumee''': "Those who would break this oath are Heretics, worthy of neither pity, nor mercy! Even now they use our lords' creations to broadcast their lies!"

''A Sangheili holds up a [[Type-50 particle beam rifle|Particle Beam Rifle]] to his chest, and an [[Unggoy]] fumbles with the [[methane tank]] of the Unggoy in front of him. Some air is released, and the second Unggoy mutters angrily at the first (turning around in the Anniversary version).''

*'''Special Operations Sangheili''': "We shall grind them into dust!"

''Note: the Hidden Subtitle appears here. It is "Scrape them as excrement from our boots!"''

'''Vadumee turns his head to face the camera, revealing he is missing the mandibles on the left side of his head.''

*'''Rtas 'Vadumee''': "And continue our march to glorious salvation!"

''The Phantoms enter Threshold's atmosphere and come upon a large Forerunner platform.''

''Scene fades back to inside lead Phantom. The Spec Ops Commander approaches 'Vadamee. They stare each other down.''

[[File:H2A-Arbiter&Rtas.jpg|thumb|300px|Rtas 'Vadumee and Thel 'Vadamee meet for the first time prior to the assault on the gas mine.]]

*'''Rtas 'Vadumee''': "This armor suits you. But it cannot hide that [[Mark of Shame|mark]]."

*'''Thel 'Vadamee''': "Nothing ever will."

*'''Rtas 'Vadumee''': "You are the Arbiter, the will of the Prophets. But these are ''my'' Elites. Their lives matter to me. Yours does not."

*'''Thel 'Vadamee''': "That makes two of us."

*'''Rtas 'Vadumee''': ''(respectful)'' "Hmmm...."

''The Phantoms fly over the Forerunner platform and descend toward another structure dangling below it on a long cable, a Gas Mine. An intense storm swirls below the structure.''

*'''Phantom Pilot''': "Leader, there is no doubt: the storm will strike the facility!"

*'''Rtas 'Vadumee''': "We'll be long gone before it arrives."

''The Phantoms fly lower, near the top of one of several towers sticking out from the center of the main structure. One deposits a group of Unggoy and a Sangheili, followed by a second one that drops two Sangheili and 'Vadamee.''

*'''Rtas 'Vadumee''': "Warriors, prepare for combat!"

'''Vadamee ignites his [[Type-1 Energy Weapon/Sword|energy sword]] and looks at it, before following his fellow Sangheili in the ''Anniversary'' version.''

'''{''Gameplay''}'''

===A Whisper in the Storm===
[[File:H2A - SpecOps deployed.jpg|thumb|300px|The Covenant SpecOps team deploys onto the gas mine.]] 

*'''Rtas 'Vadumee (COM)''': "We are the arm of the Prophets, Arbiter, and you are the blade. Be silent and swift, and we shall quell [[Sesa 'Refumee's heretic faction|this heresy]] without incident."

*'''SpecOps Elite''': "First [[lance]] in position."

''As Thel approaches the doors where the rest of the team is waiting to enter''

*'''Rtas 'Vadumee (COM)''': "The storm has masked our approach, and it should have their local [[proselytization network|Battle-net]] in disarray. We have the element of surprise... for now."

''Thel enters the airlock beyond, with a team of Special Operations Unggoy and Sangheili.''

*'''Special Operations Sangheili''': "Engage [[active camouflage]]! Reveal yourselves only after the Arbiter has joined battle with the enemy!"

''The Unggoy and Sangheili fade into their surroundings as their active camouflage is engaged.''

*'''Rtas 'Vadumee (COM)''': "You may wish to do the same, Arbiter, but take heed: your armor's system is not as...''new'' as ours. Your camouflage will not last forever."

''The team enters the next room under cloak, where Heretic Unggoy are asleep and two Heretic Sangheili patrol. If the player waits without being seen for a moment, the two Heretic Sangheili in this room will talk to one another.''

*'''Heretic Sangheili 1''': "Any word on our missing brothers?"

*'''Heretic Sangheili 2''': "Still nothing, and given [[Flood|what sleeps here]], I fear they are lost."

*'''Heretic Sangheili 1''': "Surely the [[343 Guilty Spark|Oracle]] will protect us..."

*'''Heretic Sangheili 2''': "Perhaps. But his Sentinels are too few. Better we protect ourselves!"

''The Arbiter and his team launch their attack, annihilating all the Heretics in the immediate area. Behind a wall are a few energy belts carrying [[Gas container]]s into a pit. The team eliminates the patrol in the area, then follows the energy belts to the lower levels.''

''If the player stalls:''

*'''Rtas 'Vadumee (COM)''': "There should be a ship hangar bay directly below you. Find a way down."

''The team continues on and enters an elevator. They descend into a hangar containing a [[Kai-pattern Seraph]] and a new enemy appears: the familiar [[Aggressor Sentinel|Sentinels]]. Most of them are patrolling the area, but one can be seen carrying a gas container under it and another firing a green beam at the Seraph, apparently fixing it.''

*'''Special Operations Sangheili''': "Sentinels, the holy warriors of the [[Halo Array|Sacred Rings]]. Why have they sided with these Heretics?"

*'''Heretic Sangheili 3''': ''(upon seeing the SpecOps team)'' "Sentinels, defend us!"

''During the battle in the hangar:''

*'''Phantom Pilot (COM)''': "Arbiter, clear the hangar and open this door, so I may drop the second [[lance]]!"

'''Vadamee opens the door.''

*'''Phantom Pilot (COM)''': "Hold position, I am making my approach."

''A friendly Phantom enters the Hangar Bay and deploys additional troops.''

''As more Heretics appear from below:''

*'''Special Operations Sangheili''': "More Heretics! In the passage below us!"

''After the Hangar is secure:''

*'''Rtas 'Vadumee (COM)''': "Keep heading down.  Find the leader of these Heretics."

'''Vadamee descends through the facility, fighting more Heretic Sangheili, Unggoy and Sentinels.''

''After clearing another room:''

*'''Special Operations Sangheili''': "Shall we keep moving, Arbiter?  The Heretic Leader cowers below!"

''Eventually, 'Vadamee enters a room featuring a window looking out onto a landing pad with three Heretic [[Drailaac-pattern Banshee|Banshee]]s. The Heretic Leader, [[Sesa 'Refumee]] appears.''

*'''Sesa 'Refumee''': "Deal with him, my brothers! I will defend the Oracle."

''He hops into a Heretic Banshee and flies off.''

*'''Heretic Sangheili 4''': "Its truth must not be silenced!"

''The Arbiter and the Spec Ops team defeat the Heretics and Sentinels sent to stop them.''

*'''Special Operations Sangheili''': "Onward, Arbiter!  We will secure this section of the station."

===To The Hunt===
[[File:H2A-T26AZHUD.png|thumb|250px|Driving the Banshee.]]
''The Arbiter goes outside and takes one of the remaining Banshees.''

*'''Rtas 'Vadumee (COM)''': "The Heretics are mobilizing their air forces, Arbiter. Get after their leader, but watch your back. I'm sending one of our [[Kez'katu-pattern Phantom|Phantom]]s to support you."

''After the first wave of Banshees is eliminated.''

*'''Phantom Pilot (COM)''': "The Heretics have weapons emplacements all over the facility, Arbiter. We'll take them out, one by one, until we find the Heretic Leader."

''The Arbiter follows the allied Phantom in his Banshee. As they search for the Heretic Leader, they encounter multiple Heretic Banshees, as well as hostile [[Eeo'Pimu-pattern Shade|Shade]] turrets and Heretic Unggoy armed with [[Pez'tk-pattern fuel rod gun|fuel rod gun]]s.''  

''If you take too long to head for the final emplacement:''

*'''Rtas 'Vadumee (COM)''': "No sign of the Heretic Leader or his Banshee. We must keep searching!"

''Alternately:''

*'''Phantom Pilot (COM)''': "That was the last of them - but there are more ahead."

''Or''

*'''Phantom Pilot (COM)''': "These Heretics are dead!  Onward!"

'''Vadamee nears the final emplacement.''

*'''Rtas 'Vadumee (COM)''': "We've tracked the Heretic Leader to this part of the station. Clear that landing zone and get inside."

''The Arbiter clears the platform and arrives at the door. Fades to white.''

''Level ends.''

== Trivia ==
===Glitches===
{{Main|Glitches}}
*At the beginning of the level, there will be an Elite punching buttons to open a door. If you push him away, he will continue to punch buttons in mid air, and when he is done, the door will still open.
*The two Elites that drop out of the phantom with you at the beginning of the level will follow you down to the first door, but will not follow further. They will remain at the door. If you attempt to push them into the room, the second door will not open until they leave the room.
*When you get to the hangar part go to the ledges on the sides of the rooms jump to get on them and when you move around you could hear the sounds of the doors opening. Jump down quick enough and you can get into the rooms where the enemies spawn in.
*When you open the hangar for the [[Phantom]], you could get on top of it but you will be pulled back into the level because it won't let you leave the boundaries.
*The [[Heretic leader glitch]] can be performed on this level.
*It is possible to make a Grunt invincible if he survives your first encounter with the Heretics, he can accompany you all the way to Heretic Leader's Banshee, push him over the edge onto a small ledge area, and he will be invincible, you can even test him against other enemies by skyjacking a lured Banshee to the ledge area, and kicking him out, resulting in the Grunt fighting the Heretic Elite. Note: If he is given a weaker weapon, and fires at the Heretic, the Heretic's shield will recharge quickly, resulting in a possibly endless battle.
*If you get your allies to turn against you at the beginning of this level, the Elites will try to kill you, but the Grunts will just stand there waiting for the door to open, even though they are shown as enemies.
*When you are in the [[Banshee]] you can hop out onto the [[Phantom]]. This is recommended for near the end where you can kill the Heretic Grunts from afar, or destroy Banshees if you have a Fuel Rod Gun. This is not highly recommended however as it is easy to get shot down or simply just fall off the vehicle.
*If you kill the Elite that opens the door before he gets a chance to finish, the door will open much faster.
*Going down the lift to the hangar with the Seraph fighter, you can throw plasma grenades and they will bounce without exploding. However, the grenades do explode when the elevator reaches the ground or if they stick to you or an ally.
*At the beginning of the level, when the Elite is pressing the buttons to open the door, when looking closely at his finger, you can see that it is just slightly moving around the control panel.
*At the beginning of the level, if you kill your allies before the elevator descends, no enemies will appear until you reach the elevator.
*Once you get on a Banshee fly to the right and you will see a small "bridge”, get out of the banshee and look around and you will see a red door that absorbs all shots fired at it (best done with a [[Fuel Rod Gun]] and other explosives). It will also appear in the Oracle but when approached close-up the texture will appear.
*Oddly enough,when the Phantom drops off reinforcements in the hangar, there is a possibility/glitch where it won't drop any or maybe one.

===Easter eggs===
[[File:HTMCC-H2A Grunt Birthday Party 2.jpg|thumb|Heretic Unggoy dancing around the Grunt Birthday Skull in ''Halo 2: Anniversary''.]]
{{Main|Easter eggs}}
*The [[Grunt Birthday Party Skull]] can be found on this level.
*If you manage to skyjack a Banshee or blow another Banshee up, you will notice the Heretic Elite has a Plasma Rifle equipped, instead of the Covenant Carbine. This could just be a weapon change for the pilot, maybe because he needed a lighter weapon to fly in the Banshee so it doesn't make it too uncomfortable for him. However, there's an equal chance it's an Easter egg, since not many players would pay attention to the actual dead body.
* The fourth terminal is a Forerunner terminal in the room bisected by two Forerunner gas canister conveyors, at the top of the ramp in the far right of the room.

===References===
*The soundtrack of the game, "[[Follow]]" by Incubus, can be heard on this level although without any vocals, shortly after the player is able to get in a Banshee. It was replaced by ''[[Follow In Flight]]'' in ''Halo 2: Anniversary''.
*The map [[Colossus (map)|Colossus]] is also located at the gas mine area, where the storm could be seen.
*When the [[SpecOps Grunt]] says, "Shh! Me hunting He-wa-tic.", he's making a reference to the famous Looney Tunes quote, "Shh! Be vewy vewy quiet! I'm hunting wabbits!".

===Miscellaneous===
*During the starting cutscene if you have subtitles enabled, there is a deleted line of dialogue that is never spoken, but wasn't removed from the subtitles. The line reads: "Scrape them as excrement from our boots".
*During the [[Banshee]] part, you can get out of your Banshee and land on the [[Phantom]]. This is hard to balance on, and is recommended to use at the end of the part as there is a high possibility to fall off.
*During the Banshee fight, it is possible to exit your Banshee and immediately board an enemy Heretic Banshee. This however, is quite a difficult tactic. When you do, the Elite inside will have a Plasma Rifle.
*Should the player watch the Phantoms that drop off the troops at the beginning of the level when they go out of view zoom in with your binoculars they will fall and spin out of control and hit the lower part of the level. If the player has the Acrophobia skull enabled they can fly out to the Phantoms and will be prompted to flip “Banshee.” This is likely a placeholder as the player cannot pilot a Phantom in Halo 2 through normal means.
*Many of the Grunt dialogue in this level is some of the most strange and humorous, Including ''If we stand here any longer, we be on date!'' and ''Hard to tell, but me no female''. It's the first official time you can hear them clearly, and can listen to the strange things they say, because up until now, Grunts have been against you.
*This level has more [[Fuel Rod Gun]]s than any other level in the [[Halo (series)|Halo]] trilogy.
*If you search around the station, you can find the bridge that leads from the labs to the central part of the station, which is the same that you use in the next level.
*This is the first level of the Halo series that you can play as the [[Thel 'Vadam|Arbiter]] and use the Sentinel Beam and the Covenant Carbine.
*This is the first level that includes [[Heretics]].
*The music that plays near the end of the level when the Heretic Leader escapes (before you take off in the Banshee) was not included on the [[Halo 2: Original Soundtrack|OST]]. It somewhat resembles the last part of [[Sacred Icon Suite]].
*When moving down the elevator, the Elite you are farthest from is the one that will point out the Sentinels.
*The large windows in the last room of the level are actually shut outside and you can't see through them even though from the inside you can see. Also, on the outside of the window your reticule will still change color between the normal color to green and red between friendlies and enemies even though you can't see through the windows.
*At the part with the Banshee, you can skip the long air battle with the Heretics and go directly to the area where the level ends.
*At the Banshee part, more Banshees can be seen on platforms with Heretics on them. If your Banshee is destroyed (by you or the Grunts), then another one spawns when you turn around. This will be infinite. This is probably so that if the player makes it there with the Banshee destroyed, then they won't get stuck.
*If you hide in the hangar and watch the Sentinels, you will see one firing a greenish beam at the Seraph, like the beams of the Constructor Sentinels on the Sacred Icon level. This indicates that the Seraph is undergoing repairs.

===Production notes===
*Originally, this level was supposed to take place on Threshold's moon, [[Basis]].
*[[Joseph Staten]] revealed on the ''Halo 3 Legendary Edition'' bonus disk that originally the Heretics including the Heretic Leader were all going to be [[Hunters]].
*The level's working title was "The Alpha Gas Giant".<ref name="spacejelly">[http://www.ausgamers.com/features/read/3365947 '''AusGamers''': ''AusGamers Destiny Developer Interview with Dave Dunn'']</ref>
*Bungie environment artist [[David Dunn]] experimented on having an ambient lifeform known as the [[space jellyfish]] float in Threshold's atmosphere. However, this concept was eventually abandoned.{{Ref/Reuse|spacejelly}}
